Member predicate BitField::getDeclaredNumBits
Gets the value which appeared after the colon in the bitfield declaration.
In most cases, this will give the same value as getNumBits
. It will
only differ when the value after the colon is larger than the size of
the variable’s type. For example, given int32_t x : 1234
,
getNumBits
will give 32, whereas getDeclaredNumBits
will give
1234.
